Hi,

I have a image_map like this one:
cylinder { <0,0,0>,<0,2.5,0>, 0.40
  texture{
   pigment{ image_map{ png "mypic.png"
    map_type 2 // cylindrical mapping
    once interpolate 2 }
   }
   scale <0.5,1,0.5>
  }
}

The image is wrapped around 360 deg of the cylinder.
How can I wrap it only around half of the cylinder (180 deg) or how can I
map the image only in an arbitrary degree sector?

I fumbled around with scaling the texture, but scaling x and z does not
have any effect on the result.

Any ideas?

Thanks for help!

  Use planar mapping instead, scale the image to half in the x-direction
and then apply a cylindrical warp to the pigment.
